The Pokemon Go Halloween celebration was one of the first in-game events to be introduced to the Niantic app last year.

And according to Slashgear sources, the Halloween event will return in October 2017.

Last year's Halloween event saw an increase in Ghost Type Pokemon like Ghastly, Haunter, and Gengar.

As the report points out, these three Pokemon are likely to be joined by Gen 2 Pokemon Misdreavus.

The site also suggests that Dark Pokemon will see increased spawn rates during the event, but why stop there?

Multiple Ghost Type Pokemon made their debut in Gen 3 (see the gallery below), which makes Halloween the perfect time to introduce a selection of brand new Pokemon to the game.

Pokemon Go is about to be transformed thanks to new technology available in the iPhone X, 8 and 8 Plus.

The cameras on the iPhone 8 Plus are said to have been custom tuned for AR.

But despite the improvements to AR, Niantic boss and Pokemon Go creator John Hanke still thinks the technology is limited.

In fact, Hanke thinks that AR glasses are the future of augmented reality.

Hanke thinks that while devices like Google Glass were massively flawed, AR glasses are the way forward.

"Glasses are coming," he said. "They are hard and it will take a while but we will get them and once we do, we won’t go back."

Hanke said that once the social implications of such a device are ironed out, AR glasses will transform the way we interact with the world.

"Imagine buildings, offices, homes, cities and transportation with live, dynamic interfaces customized to you and what you want to do.

"The billions of dollars a year that we spend on physical signs, directories, schedules, and all of the other ‘UI’ that we need to navigate the physical world won’t be needed and will be replaced with digital overlays with far greater functionality.
